Wiper blade

ABSTRACT

This invention relates to a wiper blade ( 20 ) having a connecting part ( 32 ) which is mounted on a carrying element ( 24 ) of the wiper blade ( 20 ) and has a pivot pin ( 42, 96, 106, 138, 146, 164, 178 ) of a joint ( 30 ) whose free end is connected to a wiper rod ( 28, 70, 80, 90, 118, 136, 150 ). It is proposed that the joint ( 30 ) includes a cap ( 54, 114, 128, 160, 190 ) which covers the connecting part ( 32 ) and is attached to it, and during operation the wiper blade ( 20 ) and the wiper rod ( 28, 70, 80, 90, 118, 136, 150 ) are secured in the installed position.

STATE OF THE ART

This invention relates to a wiper blade according to the preamble ofclaim 1.

Known windshield wipers have a wiper arm sitting on a wiper shaft whichis driven by a wiper motor. A wiper blade is connected to the free endof the wiper arm in an articulated joint. It usually has a multisectionbracket system with a central bracket to which are hinge-connectedsubordinate brackets, at least some of which hold a wiper strip withclaws at their ends. Wiper blades without a joint are also known;instead of the supporting bracket system, these have an elastic carryingelement that is made of plastic and is resilient in the directionperpendicular to the windshield. To improve the spring property, it mayhave at least one spring bar made of spring steel. In the unloadedstate, the carrying element has a greater curvature than the windshield,so the wiper strip is in contact with the windshield with a suitablepressure distribution under the pressing force of the wiper arm.

Unarticulated wiper blades have a very low design, which is highlyadvantageous with regard to their hydrodynamic properties and the noisegenerated in the slip stream from driving. German Patent 199 24 662 A1describes a windshield wiper having an unarticulated wiper blade whichis connected to a wiper arm in an articulated joint using a so-calledsidelock system comprising a two-part connecting piece, the first partof which has a block section with a bearing bore and surrounds thespring strips, which serve as the carrying element, laterally and frombeneath with integrally form-fitting elements. The second part isattached to the free end of the wiper arm which has a U-shaped profilethat is open toward the windshield. A pin is inserted laterally into thesecond part so that it runs across the longitudinal direction of thewiper arm and points toward the wiper blade; the pin is then pivotablymounted in the bearing bore of the first part of the connecting piece.

A bridge is arranged on the second part of the connecting piece inparallel with the pin and offset in the longitudinal direction, thisbridge being bent at its free end toward the side of the pin. In anassembly position in which the wiper blade is held across thelongitudinal direction of the wiper arm, the pin may be pushed into thebearing bore of the connecting part. When the wiper blade is thenrotated in parallel with the longitudinal direction of the wiper arm,the bridge extends beyond the wiper blade and locks it at its bent end,so that lateral guide faces of the block-shaped section of the firstpart of the connecting piece are guided in the installed state betweenthe bent end of the bridge and an opposing face of the second part. Inthe operating position of the wiper blade, the bridge dips into acorresponding groove of the first part and is approximately flush withits top side. For dismantling, the wiper blade must be pivoted in theopposite direction until the bent end is disengaged and the wiper bladecan be pulled away from the pin.

German Patent 28 30 508 A1 describes a wiper device for automotivewindshields which has a wiper blade to which a pivot pin is fixedlyconnected. The pivot pin runs in a plane which is essentially parallelto the windshield, and the pivot pin is rotatably mounted in a bearingbore in the wiper arm. In order for the pivot pin not to slip out of thebearing bore during a wiping movement, the wiper blade is locked in theaxial direction of the pivot pin with respect to the wiper arm by thefact that a projecting shoulder in an extension of the wiper arm engagesin a groove in the protrusion which is fixedly connected to the wiperblade at the side of the blade. The outside flank of the groove forms ashoulder against which the protrusion is in contact in the operatingposition and thus locks the wiper blade axially to the pivot pin.

ADVANTAGES OF THE INVENTION

According to this invention, the joint includes a cap which covers andis attached to the connecting part. During operation the cap covers thewiper blade and the wiper rod in the installed position. This yields avery shallow connection between a preferably unarticulated wiper bladeand a wiper rod, with the connecting parts for left-hand steeringvehicles being the same as those for right-hand steering vehicles. Onlythe wiper rod is designed in mirror image. The inventive design permitsnumerous variants with free room for design innovation, so that thewiper blade can be adapted to numerous models of vehicles. The wiper roditself can be kept simple because most functions used for adapting awindshield wiper to a motor vehicle are concentrated on the connectingpart and the pivot pin.

The cap expediently has a pocket on its side facing the wiper rod; thispocket is open toward the windshield and toward the wiper rod in thelongitudinal direction of the wiper rod and extends beyond it laterally.The pocket may be situated in the extension of the wiper rod, so that inthe operating position, an extension of the wiper rod beyond the pivotpin, engages in the pocket of the cap. The pocket may also be situatedin front of the pivot pin as seen in the longitudinal direction from thedrive side of the wiper rod, whereby it includes the wiper rod on thedrive side to the pivot pin. The cap and the wiper rod may therefore beshorter.

When the wiper rod is pivoted by approximately 90° in relation to thewiper rod, the extension of the wiper rod and/or the wiper rod itselfcomes out of the pocket and the wiper rod can be bent by the pivot pinattached to the wiper rod. Assembly then takes place in the oppositedirection.

Instead of a pocket, the cap may have a guide pin, which is guided in afork at the end of the wiper rod.

To improve wiping quality, a spoiler is usually attached to the carryingelement on both sides of the connecting part. The cap connects the twoparts of the spoiler harmonically by the fact that it is connected tothe parts by connecting profiles, thus essentially forming a continuousspoiler with good flow conditions for the slip stream. The wiper rod hasa shallow rectangular cross-sectional profile, the long side of whichruns approximately parallel to the windshield, so it supports thefunction of the spoiler when it is arranged on the oncoming flow side.The connecting part in the form of a sheet metal claw may be made ofmetal or plastic. It has a back running parallel to the carryingelement, catch projections being integrally molded on the longitudinalsides of this back for simple assembly, so that it can be clipped acrossthe carrying element. The connecting part has two side faces that faceaway from the carrying element. They have receiving openings for thepivot pin and are interconnected by a bearing tube when the pivot pin isrotatably mounted in the connecting part. The side faces have catchrecesses or catch holes in which the catch noses of the cap engage tofacilitate assembly of the cap. In addition, the cap may be held inplace by a clip which surrounds the bearing tube. The cap mayadditionally be secured by a free end of the pivot pin protruding abovethe side face and engaging in a recess in the side wall of the cap.

The wiper rod may run above the pivot pin, in the same plane as thepivot pin or beneath the pivot pin. In the first case or the secondcase, it is expedient for the end that protrudes beyond the pivot pin tobe bent or beveled toward the rubber profile of the wiper blade, so thatthe cap with its pocket can be designed to be lower. In the third case,the wiper rod may be designed to be straight. It creates particularlyfavorable oncoming flow conditions because it lengthens the underneathside of the spoiler profile and is only a short distance away from thewindshield.

If the pivot pin is rotatably mounted in the connecting part, it isfixedly connected to the wiper rod at an end which protrudes out of theconnecting part. This connection may be a material connection, e.g., aconnection formed by welding, or a form-fitting or friction-lockedconnection, e.g., formed by riveting, pressing or the like.

According to one embodiment of this invention, on the end that isprovided for the wiper rod, the pivot pin has a flat head in which thereare rivet holes for rivets. In this case the wiper rod has correspondingrivet holes and is riveted to the pivot pin. In another embodiment, thepivot pin has a flat head with an integrally molded polygon, e.g., atriangular, quadrangular or hexagonal shape protrudes across the pivotpin, is pressed into a corresponding opening on the wiper rod and issecured on its projecting end by wobble riveting. Wobble riveting is ariveting method in which the riveting tool executes a wobble motionduring riveting. Before assembly, the wiper rods and heads of the pivotpins are painted black.

In another embodiment, the pivot pin has a head with a slot toaccommodate the flat wiper rod which is secured in the slot by means ofa cross pin or a rivet. As an alternative to that, the wiper rod mayhave a hub in the area of the pivot pin, encircling the pivot pin andbeing secured on it by a cross pin.

According to another embodiment, the flat wiper rod is rotated byapproximately 90° at the end so that a wide side of one end lies acrossthe pivot pin. The end has a receiving bore for a pivot pin with acollar to which a flanged seat is connected, the receiving bore beingpressed onto it and the seat being secured by a tamped disk. The endprotruding beyond the pivot pin is beveled toward the rubber profile ofthe wiper blade and engages in a respective pocket of the cap. Thisembodiment has a short design length of the pivot pin, but theadvantageous position of the wiper rod with respect to the spoiler isnevertheless retained in most of the area of the wiper rod.

DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

An unarticulated wiper blade 20 has a rubber profile 22 which isattached to a flat carrying element 24, usually consisting of one or twospring strips embedded in the top part of the rubber profile 22. Forarticulated connection of the wiper blade 20 to a wiper rod 28 of awiper arm (not shown in detail here), a joint 30 is provided in themiddle area of the wiper blade 20. This joint has as a connecting part asheet metal claw 32, the back 34 of which spans the carrying element 24and is attached to it with catch noses 36. The catch noses 36 can bepushed over the carrying element 24 in the longitudinal direction ordesigned as a clip connection and clipped across the carrying element 24by elastic deformation. Between the catch noses 36, which are providedlaterally on the ends of the sheet metal claw 32, side faces 38 are adistance away from the rubber profile 22 on the longitudinal sides 66 ofthe sheet metal claw 32. They hold a bearing tube 40 which runs acrossthe wiper blade 20 and runs approximately parallel to a windshield (notshown). A pivot pin 42 is inserted into the bearing tube 40 andprotrudes with a head 44 out of the bearing tube 40 on one side towardthe wiper rod 28.

The wiper rod 28 has a rectangular cross section, with the longer sidesrunning approximately parallel to the pivot pin 42. In the embodimentsaccording to FIGS. 1 through 3, the wiper rod 28 engages in the slot 46on the head 44 of the pivot pin 42 and is secured by a cross pin 48. Thewiper rod 28 protrudes beyond the slot 46 with a finger 52. The finger52 is narrower than the wiper rod 28 and is situated on the side of thewiper rod 28 which faces the wiper blade 20.

When seen in the longitudinal direction, the parts of a spoiler 26 areattached to the carrying element 24 on both sides of the sheet metalclaw 32, thus increasing the pressing force on the windshield due to theslip stream when there is an oncoming flow from driving. The sheet metalclaw 32 is covered by a cap 54, which is harmonically contiguous withthe parts of the spoiler 26 with the connecting profiles 64. The cap 54is detachably attached to the sheet metal claw 32. To this end, it hascatch noses 56 on the inside of its side walls 60, engaging incorresponding openings 104 (FIG. 11) and/or recesses in the sheet metalclaw 32. In its central area, it also has a clip 58 for fastening ontothe bearing tube 40. The pivot pin 42 protrudes at its end which facesaway from the head 44 (FIG. 2) beyond the side face 38, where this endengages in a recess in the side wall 60 of the cap 54 (FIG. 3) and thussupports its hold on the sheet metal claw 32.

On the side of the wiper rod 28, the cap 54 has a pocket 62 which isopen toward the windshield (FIG. 3), the finger 52 of the wiper rod 28engaging in said pocket in the operating position, in which the wiperblade 20 is in contact with the windshield. An outside wall 68 of thepocket 62 prevents the wiper rod 28 with its finger 52 from movingoutward, so that the pivot pin 42 is locked in the axial direction. Thepocket 62 is largely covered by a cover 50 which sits on the pivot pin42 and is in harmonic contact with the contour of the wiper rod 28 andthe cap 54. The cover 50 is at the same time an impact protection and/ordamping element. It prevents damage to the windshield if the wiper arminadvertently strikes the windshield when changing the wiper blade 20.

The descriptions of FIG. 4 through FIG. 6 show wiper rods 70, 80 whichare attached to one end of the pivot pin 42 by means of welds 74. Thewiper rod 70 according to FIG. 4 runs above the pivot pin 42 andprotrudes at an end 72, which is bent toward the rubber profile 22,beyond the joint axle 42. The bent end 72 engages in a pocket 76 of thecap 54 when the wiper blade 20 is in the operating position shown here,where the edge 78 of the cap 54, which faces the wiper arm 70, runs sothat the wiper blade 20 can easily be pulled away from the pivot pin 42when in a position rotated by a approximately 90° in the direction ofthe arrow. In this position, the wiper blade 20 is also installed byplacing it on the pivot pin 42 and then pivoting it in the oppositedirection. The wiper blades 20 according to FIG. 1, FIGS. 5 through 7,FIG. 10 and FIG. 11 are installed and dismantled in the same way. Due tothe bent end 72, the pocket 76 may be designed to be flat, so that thewind resistance is reduced and the visual impression is improved.

The same effect is achieved when the wiper rod 80 runs beneath the pivotpin 42 in the embodiments according to FIG. 5 and FIG. 6 and itsstraight end 82 which is lengthened beyond the pivot pin 42 engages in apocket 84 in the cap 54. Here again, the edge 86 of the pocket 84 isdesigned so that installation or dismantling is readily possible in thepivoted installation position. In the embodiments according to FIG. 4and FIG. 5, the wiper blade 20 must be rotated by approximately 90° forinstallation, but in the embodiment according to FIG. 6, the wiper blade20 can be installed and dismantled even at a smaller pivot angle. Thisis achieved by the fact that the edge 88 of the pocket 84 runs at asmaller angle to the longitudinal direction of the wiper blade 20.

The embodiment according to FIG. 7 permits a very narrow joint 30 inthat the wiper rod 90 is set at an angle of approximately 90° in thelongitudinal direction at its end 92, so that in the area of the pivotpin 96, the longer sides of the rectangular profile of the wiper rod runacross the pivot pin. The end protruding beyond the pivot pin 96 has abevel 94, which is inclined toward the rubber profile 22 and engageswith the bevel 94 in a pocket 122 of the cap 54. For installation anddismantling, the edge 124 of the pocket 122 is designed accordingly. Thepivot pin 96 (FIG. 9) has a flanged seat 100 against which the wiper rod90 is pressed up to a collar 98 with a receptacle opening and is securedby a washer 102.

In the embodiments according to FIG. 10 and FIG. 11, the end of thewiper rods 118 protruding beyond the pivot pin 42 is designed as a fork112 which in the operating position illustrated here holds a guide pin116 of the cap 114. In order to be able to design the cap 114 to beflat, it is expedient for the fork 112 to be inclined toward the rubberprofile 22. In the embodiment according to FIG. 1, the wiper rod 118according to FIG. 16 engages in a slot 46 in the head 44 of the pivotpin 42 and is secured by a cross pin 48, but the wiper rod 118 accordingto FIG. 11 has a hub 120 which sits on the free end of the pivot pin 42and is secured by a cross pin 48. Essentially the wiper rod 118, likethe wiper rods in the embodiments described previously, may be welded tothe pivot pin 42.

The embodiments according to FIG. 12 through FIG. 15 and FIG. 18 areidentical to the embodiments according to FIG. 5 and FIG. 6. Here again,the wiper rods 80 and 136 run beneath the pivot pins 42 and/or 106 and138. Although the wiper rod 80 according to FIG. 12 and FIG. 13 iswelded to the free end of the pivot pin 42, the pivot pin 138 accordingto FIG. 14 and FIG. 15 has a flat head 140 with two rivet holes 142connected by rivets 144 to the wiper rod 136 (FIG. 15). The pivot pin106 (FIG. 17) has a flat head 108 with an integrally molded square shape110, the head being pressed into a corresponding opening in the wiperrod 136 and optionally being riveted in a wobble [riveting] method (FIG.18).

The caps 54 for the embodiments according to FIG. 12 through FIG. 15 andFIG. 18 have pockets 126 on the side facing the wiper rod 80, 136, saidpockets encompassing the wiper rod 80, 136 on its dry side in front ofthe pivot pin 42, 106, 138, so that the wiper rod 80, 136 need notprotrude beyond the pivot pin 42, 106, 138. This permits very flatdesigns for the wiper blades 20 whereby the cap 54 may be designed to bevery flat and tight. Between the pocket 126 and the front part of thecap 128, only a small installation window 132 remains open in theexterior side wall. The installation windows 132 according to FIG. 12and FIG. 14 have an edge 130 running approximately perpendicular to therubber profile 22, but the edge 134 of the installation window 132 isinclined toward the rubber profile 22 according to FIG. 13, so that thewiper blade 20 may be installed and dismantled at an angle which issmaller than 90°. For dismantling, the wiper blade 20 must be pivoted inthe direction of the arrow, as shown in FIG. 12.

In another embodiment, the pivot pin 178 (FIGS. 20, 21) has twodiametrically opposed wings 180, 182 facing the wiper rod 28, 90 andextending radially to the pivot pin 28, 90 [sic; 178] and in thelongitudinal direction of the respective wiper rod 28, 90. The pivot pin178 according to FIG. 20 like the pivot pin 42 according to FIG. 1 has aslot 46 in a head 44 into which the wiper rod 28 is inserted and securedby a cross pin, e.g., a rivet. The pivot pin 178 according to FIG. 21has a rivet pin 178 [sic] on the end, with which it is attached to thewiper rod 90, which is rotated by 90° in the longitudinal direction likethe wiper rod 90 according to FIG. 8. In both cases, in the installedposition of the wiper blade 20, the wings 180, 182 engage in suitablyaligned pockets 184, 186 of a pocket 190 (FIG. 19) in the manner of abayonet closure. By rotating the wiper blade 20 by 90°, the bayonetclosure can be released for dismantling or closed for installation.

With the embodiments described so far, the pivot pin 46, 96, 106, 138 isrotatably mounted in the bearing tube 40 of the sheet metal claw 32 andis connected to the wiper rod 20, 70, 80, 90, 118, 136, but the pivotpin 146, 164 is in a rotationally fixed connection to the sheet metalclaw 32 and is rotatably connected to the wiper rod 150, e.g., by beingheld in corresponding openings in the side faces 38 with an out-of-roundcross-sectional profile in the form of a polygon or a flattenedcylinder. In the embodiment according to FIG. 24, the pivot pin 146 hasa half-round cross-sectional profile with a flattened surface 148 facingthe rubber profile 22. It is inserted in a rotationally fixed mannerinto openings in the side faces 38 of the sheet metal claw 32 and on itsend projecting laterally to the wiper rod 150, it carries a bearingbushing 154 in a rotationally fixed mount, said bushing having on itsouter circumference a cylindrical area 156 and optionally having aflattened area 158 toward the rubber profile 22. A suitably bent end 152of the wiper rod 150 is rotatably mounted on the bearing bushing 154(FIG. 23). The bent end 152 may also be mounted directly on a round orhalf-round profile part of the joint shaft 146, 164. The bearing bushing154 and the end 152 of the wiper rod 150 are guided in a bearing pocket162 of a cap 160. The cap 160 is attached by means of catch noses 56 anda clip 58 on the sheet metal claw 32 and/or on the pivot pin 146. Inaddition, the pivot pin 146 protrudes beyond the bearing bushing 154 andengages in recess 176 in the cap 160. The wiper blade 20 may beinstalled on the wiper rod 150 by rotating it with the installed cap 160to the extent that the bent end 152 can be threaded between the cap 160and the bearing bushing 154.

The variant according to FIG. 24 has a pivot pin 164 with a fasteningarea 166 which has an essentially rectangular cross section and alongitudinal section 168 running across the longer sides. The longersides of the cross-sectional profile run approximately parallel to thecarrying element 24. On the outer sides, catch noses 170 are provided onthe ends of the fastening area 166, protruding into an opening in therespective side face 38 and engaging with the edge of this opening. Onthe other end, the pivot pin 164 has a bearing area 172 which isbordered by two collars 174 in the axial direction. The bent end 152 ofthe wiper rod 150 is mounted on the bearing area 172 and is secured inthe installed position via the bearing pocket 152 of the cap 160.
